S32K148-Q176 FreeRTOS official example Project

Hi,

I' m working with s32k148-q176 EVB, I try to test FreeRTOS explame project,“freertos_s32k148”. But when i press the Button sw4(PIN： PTC13), the LED has no change. I add one parameter “ctr” in Interrupt function "vPort_C_ISRHandler()" ,which is in rtos.c file. I open Real Time Expressions, want to check if the interrupt ISR execute or not. When i press the Button sw4，my parameter “ctr ” is still 0.

I have no idea, how to solve it.

Here is Debug window.

Can anyone help me？

Thanks.

Liu

Hi,

I tried this demo example and add a variable similarly

When press SW4 red LED is ON and I see vPort_C_ISRHandler_cnt updating in Real Time Expression window.

Be sure you do not halt the Expression Values Refresh.

Hi,Petr,

Thanks for your reply.

This problem is not about software(code). I check the connection of switch 3 and 4 . There are some hardware problems. These two switch cannot work. I have already contactednxp after-sales service department staff.
